Been to this location a couple times, and figured I'd contribute to the reviews. I personally haven't had any 'bad' experiences some other yelpers have indicated, but I do understand what they are getting at.
I am usually in this area on Saturdays for work, so I may pop in from time to time. I'm a big fan of the drive thru at Starbucks, as I'm usually the grab and go type.
This location's baristas tends to always be 'having fun' amongst themselves, which I don't mind, but they got to get people's orders in and make the drinks! The 2 times I've been through the drive thru, I ended up waiting quite a long time as the first time, the girl taking my order didn't even know what the Roasted Tomato & Mozzarella Sandwich was... And the second time they forgot to make my drink, so I had to wait at the window as the cars behind me waited even longer (while their drinks were already done!).
They chat and joke a lot with each other, but that ultimately makes their service suffer.
